[:SOURce]:INPut:DATA:IMPedance <Impedance>
Sets the impedance of all data inputs.
The setting affects the serial data input DATA at the front of the instrument and the
serial data inputs DATA at the AUX I/O interface at the rear of the instrument.
Parameters:
<Impedance> G50 | G1K
*RST:
G1K
Example: INP:DATA:IMP G50
all data inputs are set to 50 ohm to ground.
Manual operation: See "Impedance Data Input" on page 142
[:SOURce]:INPut:DATA:THReshold <Threshold>
Sets the high/low threshold of the data inputs in the baseband section. In the case of
positive polarity, this threshold determines the point as of which a signal is high (active)
or low (inactive).
The setting affects the serial data input DATA at the front of the instrument and the
serial data inputs DATA at the AUX I/O interface at the rear of the instrument.
Parameters:
<Threshold> float
Range:
0.01 to 2
Increment: 0.01
*RST:
1
Default unit: V
Example: INP:DATA:THR 1 V
a high/low threshold of 1 volt is set at all data inputs of the base-
band section. The signal is high (active) for a signal voltage of 1
volt and higher.
Manual operation: See "Threshold Data Input" on page 142
[:SOURce<hw>]:INPut:MODext:IMPedance <Impedance>
Sets the impedance for an externally applied modulation signal.
